Abstract
The utility model discloses the fume reducing and burn-assisting device of a vertical coal-burning furnace, comprising an annular cavity air preheating chamber, wherein, an air inlet is arranged on the wall of the annular cavity air preheating chamber, a wind screen is arranged in the annular cavity of the air preheating chamber, the inner side wall of the air preheating chamber is connected with a reflection arch whose central position is provided with a fume hole ring, and 3-8 air distributing pipes which are communicated with the air preheating chamber and the fume hole ring are arranged in the wall of the reflection arch. Air passes the air distributing pipes and rises in a rotary way after preheated in the air preheating chamber, and deleterious combustible gas and combustible dust in rising burning smoke gas are sufficiently burned in rotary hot wind. The fume reducing and burn-assisting device of a vertical coal-burning furnace can increase furnace temperature and save energy source, reducing environmental pollution.
Description
The utility model belongs to small-sized coal-fired vertical boiler accessory class.
Existing coal-fired vertical heater, as vertical steam boiler, vertical type water heater boiler, vertical dual purpose steam water boiler, vertical two-purpose drinking water boiler, vertical drinking water boiler etc., because atmosphere is not filled in burning, in the residual gas of discharging, contain a large amount of harmful imflammable gas and combustible dusts, waste a part of energy, the more important thing is the serious environment that polluting.
The purpose of this utility model is: provide a kind of burning to fill atmosphere, save the coal-fired vertical heater smoke-eliminating combustion-aid device energy, that environmental pollution is little.
Technical measures of the present utility model are: by putting a smoke-eliminating combustion-aid device, this device has the cavity air preheating chamber of an annular, and an air inlet is arranged on the wall of preheating chamber, and a deep bead is arranged in the cavity of preheating chamber on the top, combustion chamber of coal-fired vertical heater; On the madial wall of air preheating chamber, connect the reflection arch that there is smoke hole ring at a center, 3-8 the wind-distributing pipe that UNICOM's preheating chamber and smoke hole ring are arranged arranged in the reflection buttress.
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is a vertical view.
4 is cavity air preheating chambers of annular among the figure, and its section can be garden shape or square, preheating chamber available metal material; There are an air inlet 5, air inlet can be arranged on the lateral wall of preheating chamber on the wall of preheating chamber; A deep bead 6 is arranged in the cavity of preheating chamber, prevent circulating of air intake; Connect the reflection arch 2 that there is smoke hole ring at a center on the madial wall of air preheating chamber, reflection arch 2 is to adopt refractory concrete to make, and reflection arch 2 adopts the combustion efficiency of taper relatively good.In the reflection buttress 3-8 wind-distributing pipe 3 arranged, one end of each wind-distributing pipe and preheating chamber 4 UNICOMs, the other end and smoke hole ring 1 UNICOM, for the intake that makes each wind-distributing pipe even, the overstriking successively of the diameter of wind-distributing pipe 3, each wind-distributing pipe 3 is tangential with smoke hole ring 1 space and connects; After making air intake by preheating like this, rise, make to be mingled with harmful imflammable gas and combustible dust are filled atmosphere in the hot blast of rotation burning in the flue gas that on the combustion chamber, rises through wind-distributing pipe rotation.
This smoke-eliminating combustion-aid device is saved the energy to improving furnace temperature, particularly to reducing environmental pollution tangible good effect is arranged.
Claims (2)
